Cognition, Brain, and Consciousness Chapter 3, 4
These chapters are about neurons and its connections, and tools for imaging the brain in the introduction of the cognitive neuroscience textbook. I come up with several random thoughts.
p63: it reads, in the history of science, new mathematical techniques often help to understand new questions. Then, what kinds of math approaches are useful or necessary to understand our consciousness and unconsciousness that the rest of us? I'd like to apply I Ching but, still need more study.
p65: While reading about a simple reflex circuit (ex. knee-jerk reflex), the idea of sleep and alertness came again in mind. I'd like to dig into those thing by researching, experimenting, and calculating, very similar to the study of nutrition. Most of us don't care about a nutrition precisely, but I think we all have some common sense of it, or automatically controlled by a food culture. Therefore, the study will improve of our sleep and alertness of everyday life. Alfred North Whitehead once said that civilization advances by extending the number of important operations
which we can perform without thinking about them.
p66: It reads, most pathways run in both directions. Recently, I'm curious why a head-phoned friend in library answers so loud. Isn't it an example of this?
p73: (wild fancy) According to the hierarchy of sensory and motor, signals could go forward and backward. Then what about the sense of time? Does the hierarchy allow time go forward and backward in an instant moment made by the floating signals of sensory?
p75: Using ambiguity of visual image, military camouflages are designed.
p120: In the significant word experiment, it uses a combination of sound and brainwave. And also, chapter 4 says, convergent methods such as EEG and fMRI are important. I should make my system a convergent logging design.
Here is quote from James Watson(co-discoverer of DNA structure): We understand the hardware, but we don't have a clue about the operating system.
